DNN中gridView中数据链接地址设定的两个实例

实例一，用HyperLink控件，数据绑定时增加链接地址：

UI代码： 

<asp:GridView ID="grdResult" runat="server" CssClass="DataGrid_Container" AllowPaging="False"    
   AutoGenerateColumns="False" BorderWidth="0"  OnRowDataBound="grdResult_RowDataBound"  >   
   <RowStyle CssClass="DataGrid_Item" />   
   <SelectedRowStyle CssClass="DataGrid_SelectedItem" />           
   <HeaderStyle CssClass="DataGrid_Header"  />           
   <AlternatingRowStyle CssClass="DataGrid_AlvternatingItem" />      
   <Columns>               
       <asp:TemplateField HeaderText="选择"  >   
           <ItemTemplate >   
               <input id="SelectId" type="checkbox" value='<%# Eval("DocId") %>' />     
               <asp:HiddenField id="DocId" value='<%# Eval("DocId") %>' runat="server" />     
               <asp:HiddenField id="DocType" value='<%# Eval("DocType") %>' runat="server" />     
            </ItemTemplate>                    
       </asp:TemplateField>   
       <asp:TemplateField  HeaderText="名称" HeaderStyle-HorizontalAlign="Left" ItemStyle-HorizontalAlign="Left" >   
           <ItemTemplate  >   
               <asp:Image ID="imgFolder" runat="server" />   
               <asp:HyperLink ID="DocName" Text='<%# Eval("DocName") %>' runat="server"></asp:HyperLink>   
           </ItemTemplate>   
       </asp:TemplateField>                           
       <asp:BoundField DataField="FileSize" HeaderText="文件大小(KB)"  />   
       <asp:BoundField DataField="CreateDate" HeaderText="修改时间" DataFormatString="{0:yyyy年MM月dd日 HH:mm}" />     
   </Columns>                 
</asp:GridView>  

 C#代码绑定方法一：

protected void Page_Load(object sender, System.EventArgs e)   
{   
    if(!Page.IsPostBack)   
    {   
        BindGridData();             
    }   
}   
private void BindGridData()   
{   
    List<DocumentInfo> di=DocumentController.GetListDocument(this.UserId);   
    if (di.Count == 0)   
    {   
        di.Add(new DocumentInfo());         
    }   
        grdResult.DataSource = di;   
        grdResult.DataBind();   
      
}     
  
//数据绑定时增加链接地址   
protected void grdResult_RowDataBound(object sender, GridViewRowEventArgs e)   
{              
    if (e.Row.RowType == DataControlRowType.DataRow )   
    {   
        HyperLink DocName = (HyperLink)e.Row.FindControl("DocName");                   
        Image imgFolder=(Image) e.Row.FindControl("imgFolder");   
        //List<DocumentInfo> di =e.Row.DataItem as List<DocumentInfo>;   
        HiddenField txtDocId = (HiddenField) e.Row.FindControl("DocId");   
        HiddenField txtDocType = (HiddenField)e.Row.FindControl("DocType");   
           
        //根据表中的列判断是否有数据   
        if (txtDocId.Value == "0")   
        {   
            int cols = e.Row.Cells.Count;   
            TableCellCollection tc = e.Row.Cells;   
            tc.Clear();   
            tc.Add(new TableCell());   
            tc[0].ColumnSpan = cols;   
            tc[0].Text = "没有找到你要的资料。";      
        }   
           
        if (txtDocType.Value.Trim().ToLower() == "fold")   
        {   
            imgFolder.ImageUrl = this.ControlPath + "images/folder1.gif";   
            string navUrl = "javascript:navurl('" + "http://" + Request.Url.Host + ResolveUrl("../Document/callIndex.aspx?FolderId=");   
            DocName.NavigateUrl = navUrl + txtDocId.Value.Trim() + "')";    
        }   
  
    }   
}  

 C#代码绑定方法二：

//绑定时设定链接地址   
protected void grdResult_RowDataBound(object sender, GridViewRowEventArgs e)   
{              
    if (e.Row.RowType == DataControlRowType.DataRow && e.Row.RowIndex >= 0)   
    {                   
        DataRowView dr=(DataRowView)e.Row.DataItem;   
        int intTabID= Common.GetTabId(PortalId, "ReceiveAccount");                    
        HyperLink likSendMsg = (HyperLink)e.Row.FindControl("OptSendMsg");   
          
        if (intTabID >= 0)   
        {   
            likSendMsg.NavigateUrl = Globals.NavigateURL(intTabID, "", "fId=" + dr["UserId"].ToString());                                    
        }    
    }   
}  

实例二，用ImageButton控件，当用户点击button时，通过事件处理程序按照DataKey的值，

进行转向链接或进行数据处理：

UI代码： 

    <asp:GridView ID="grdData" runat="server" Visible="False" CssClass="DataGrid_Container" 
        PagerSettings-Visible="false"  BorderWidth="0px"  DataKeyNames="RowId" 
        AutoGenerateColumns="False" AllowSorting="True" OnRowEditing="grdData_RowEdit" OnSorting="grdData_Sorting"
        OnRowDeleting="grdData_RowDeleting" >
        <AlternatingRowStyle CssClass="DataGrid_AlvternatingItem" />
        <RowStyle CssClass="DataGrid_Item" />
        <HeaderStyle CssClass="DataGrid_Header" />       
        <Columns>
            <asp:TemplateField HeaderText="执行操作">
                <ItemTemplate >                   
                    <asp:ImageButton ID="BtnUpdate" runat="server"  ToolTip="编辑" CommandName="Edit" ImageUrl="~/images/edit.gif" />                        
                    <asp:ImageButton ID="BtnDelete" runat="server" CausesValidation="False" CommandName="Delete"
                            ToolTip="删除" OnClientClick="return confirm('确认要删除此记录吗？')" ImageUrl="~/images/delete.gif"/> 
                </ItemTemplate>
            </asp:TemplateField>            
        </Columns>
    </asp:GridView>

C#代码：

        protected void grdData_RowEdit(object sender, GridViewEditEventArgs e)
        {           
            string RowId = grdData.DataKeys[e.NewEditIndex].Value.ToString();           
            Response.Redirect(EditUrl("RowId",RowId, "EditForm"));
        }

        protected void grdData_RowDeleting(object sender, GridViewDeleteEventArgs e)
        {
            if (ListController.DeleteRow(TableName, grdData.DataKeys[e.RowIndex].Value.ToString()))
            {
                Common.ShowSuccessFacebox("删除成功！", Page, 0);
            }
            else
            {
                Common.ShowFailureFacebox("删除失败！", Page);
                return;
            }              
            grdData.EditIndex = -1;            
            BindData();
        }
